因为阻尼器的安装需要占用一定空间，采用两个阻尼器就需要加大轨道的尺寸来放置阻尼器，这样会导致轨道的结构尺寸增大，另外也造成淋浴门成本增加。
发明概述
技术问题
现有技术的滑动式淋浴门中需要安装两个阻尼器来分别对活动门板开关门两个方向的运动提供缓冲，阻尼器占用空间较大，淋浴门的成本较高；此外现有技术的阻尼器结构复杂。

一个优选的方案是，阻尼缸包括两个分离的缸体，阻尼缸的两个缸体与两根活塞杆一一对应；或，阻尼缸的缸体为双腔缸体，阻尼缸的两个缸腔与两根活塞杆一一对应。
另一个优选的方案是，卡合件上还设有第二导向件，第一导向件与第二导向件之间的距离大于连接板的厚度，第二导向件抵接于连接板的朝向拉簧的一侧。
进一步的方案是，卡合件上还设有第三导向件，第三导向件抵接于连接板的背向拉簧的一侧，沿第二方向，第二导向件位于第一导向件与第三导向件之间。
再一个优选的方案是，拉簧的沿第二方向的两端分别与两个卡合件连接。
又一个优选的方案是，拉簧包括第一拉簧和第二拉簧，一个卡合件与第一拉簧连接，另一个卡合件与第二拉簧连接，第一拉簧及第二拉簧均与安装架连接。
还一个优选的方案是，沿第二方向，两个第二卡齿位于两个第一卡齿之间，第一卡齿上具有倾斜引导面，倾斜引导面位于第一卡齿的背向第二卡齿的一侧；沿第三方向，倾斜引导面位于第一卡齿的背向拉簧的一侧。
进一步的方案是，第二卡齿为弯折结构，第二卡齿包括第一弯折段和第二弯折段，沿第二方向，第一弯折段的远离第二卡齿的一端与卡合件的主体部分连接，第一弯折段的靠近第二卡齿的一端与第二弯折段连接；沿第三方向，第二弯折段从第一弯折段上向拉簧一侧弯曲，第二弯折段的朝向拉簧的一侧与卡合件的主体部分之间具有间距；倾斜引导面设于第一弯折段上。卡合件的主体部分是指卡合件的去除第一卡齿之外的部分。
更进一步的方案是，第二卡齿还包括第三弯折段，沿第三方向，第二弯折段的朝向拉簧的一端与第三弯折段连接；卡合件上设有限位结构，限位结构具有开 口朝第二卡齿的限位腔，第二弯折段穿设于限位腔的开口中，第三弯折段位于限位腔中，限位结构限制第三弯折段脱离限位腔。

问题的解决方案
发明的有益效果
有益效果
本发明的双向阻尼器能够在正反两个方向上提供缓冲，这样本发明的淋浴门组件中，通过本发明的双向阻尼器与安装基体上的限位件配合作用，使得活动门板开关门过程均能得到有效缓冲，有利于淋浴门组件的结构简洁，其中安装基体可以是门框和导轨等。
本发明的双向阻尼器中，阻尼缸、拉簧及卡合件等均隐藏于第一架板与第二架板之间，这有利于双向阻尼器的外部结构简洁；此外采用连接板将拉簧与阻尼缸隔开，避免拉簧与阻尼缸互相影响，有利于提升双向阻尼器的可靠性。
此外，由于导向槽、第一导向件与第二导向件的设置，有利于使卡合件沿对应的导向槽稳定地运动，进一步提升双向阻尼器的可靠性。
本发明由于在第一卡齿上设置倾斜引导面，使得在活动门板开关门过程中卡合件到达限位件时，即使第一卡齿与限位件产生了干涉，限位件也能在倾斜引导面的引导下迫使第一卡齿向拉簧一侧运动或变形，继而使第一卡齿顺利通过限位件处，有利于双向阻尼器持续保持正常运行。
本发明中拉簧的数量可以只设置一根，这样有利于减少双向阻尼器的零件数量，降低双向阻尼器的生产难度，有利于双向阻尼器的结构简洁，有利于提升经济性。
本发明的第一卡齿设为弯折结构，这样即使卡合件在到达限位件时位于主体段，限位件也能通过将第一卡齿挤压变形迫使第一弯折段向拉簧一侧弯曲变形，继而使第一卡齿通过限位件，保证限位件能够顺利到达卡合件的卡口中，保证 卡合件在与限位件脱离时已经顺利回位至延伸段，有利于双向阻尼器长期保持正常运行。
在限位结构的限制下，除了第一弯折段能进行有限的变形以及恢复形变之外，限位结构限制第二弯折段在滑动方向上变形，并通过限制第三弯折段脱离限位腔来限制第一弯折段的变形范围，保证第一卡齿的形态稳定，保证第一卡齿的变形可控。
连接板通过与第一导向件、第二导向件及第三导向件的抵接，来限制卡合件在导向槽中的形态，避免卡合件出现翻转，有利于保证卡合件的状态稳定。

发明实施例
本发明的实施方式
双向阻尼器及淋浴门组件实施例：
本实施例采用如图1所示的坐标系进行说明。
请参照图1及图2，本实施例的淋浴门组件包括活动门板100、门框(图中未示出)和本实施例的双向阻尼器200，活动门板100相对门框沿Y轴方向滑动，Z轴方向为竖直方向，双向阻尼器200安装在活动门板100的顶部，门框上设有两个限位件(图中未示出)。本实施例的双向阻尼器200包括一个安装架1、一个拉簧2、两个阻尼缸3和两个卡合件4，两个卡合件4分别为第一卡合件4a和第二卡合件4b，两个限位件与两个卡合件4一一对应，各限位件位于对应卡合件4的运动路径上。
请参照图3，安装架1包括第一架板11、第二架板12、连接板13和两个固定块14，连接板13包括主体段131和两个延伸段132，两个延伸段132分别为第一延伸段132a和第二延伸段132b，第一架板11、第二架板12及连接板13均为长条板体，第一架板11、第二架板12及主体段131的长度方向均沿Y轴方向，两个延伸段132连接于主体段131的沿Y轴方向的两端，两个延伸段132均从主体段131向Z轴负向弯曲；第一架板11与第二架板12沿X轴方向间隔分布，第一架板11与第二架板12主面相对。
请参照图3及图4，连接板13及固定块14均连接于第一架板11与第二架板12之间，两个固定块14分别位于双向阻尼器200的沿Y轴方向的两端，第一架板11、第二架板12和两个固定块14围成安装腔，连接板13将安装腔分隔成上腔18和下腔19，上腔18位于连接板13的Z轴正向一侧，下腔19位于连接板13的Z轴负向一侧，两个阻尼缸3的缸体均固定在上腔18中，两个阻尼缸3沿Y轴方向相背地设置，两个阻尼缸3的活塞杆31轴线重合，两根活塞杆31分别为第一活塞杆31a和第二活塞杆31b，两根活塞杆31均沿Y轴方向伸缩，且两根活塞杆31的伸缩方向相反，两个卡合件4一一对应地铰接在两根活塞杆31上。
优选地，请参照图3至图5，上腔18的沿Y轴方向的中部设有隔板15，两个阻尼缸3分别置于隔板15两侧。具体地，阻尼缸3的缸体上开设有限位槽33，安装架1上设有第一限位凸起16和第二限位凸起17，第一限位凸起16嵌于限位槽33中，沿Y轴方向，阻尼缸3的缸体限制于第二限位凸起17与隔板15之间。这样有利于阻尼缸3在安装架1上安装固定牢固。
可选择地，两个阻尼缸3均为气液阻尼缸，阻尼缸3的阻尼方向为活塞杆31向缸腔内回缩的方向。
具体地，请参照图2及图3，固定块14上开设有沿Z轴方向贯通的安装孔，便于通过螺钉将安装架1固定在活动门板100上。
请参照图3，连接板13上开设有两个贯通连接板13的导向槽133，两个倒下你给草133分别为第一导向槽133a和第二导向槽133b，两个导向槽133位于连接板13的沿Y轴方向的两端，两个导向槽133一一对应地贯通两个延伸段132，导向槽133从延伸段132延伸至主体段131，导向槽133在主体段131上沿Y轴方向延伸，两个 卡合件4与两个导向槽133一一对应，各卡合件4可滑动地安装在对应的导向槽133中。
请参照图6，卡合件4上设有第一卡齿41、第二卡齿42、第一导向件44和第二导向件45，在卡合件4滑动至主体段131时，第一卡齿41与第二卡齿42均从卡合件4上沿Z轴正向延伸，第一卡齿41与第二卡齿42均露出至安装架1外，第一卡齿41与第二卡齿42沿Y轴方向间隔分布，第一卡齿41与第二卡齿42之间形成卡口46，沿Y轴方向，两个第二卡齿42位于两个第一卡齿41之间。
请参照图4及图6，第一导向件44与第二导向件45均从卡合件4上沿X轴方向凸出，第一导向件44及第二导向件45均为柱体，第一导向件44与第二导向件45之间的距离大于连接板13的厚度，第一导向件44抵接于连接板13的背向拉簧2的侧壁上，第二导向件45抵接于连接板13的朝向拉簧2的侧壁上，拉簧2位于下腔19中，拉簧2连接于两个卡合件4之间。
如果卡合件4上仅设置第一导向件44和第二导向件45两个导向结构，那么在第二卡齿42与限位件抵接时，限位件与第二卡齿42之间的挤压力可能使卡合件4绕其与活塞杆31的铰接处翻转，导致导向件4与限位件脱离抵接，导致双向阻尼器失效，因此，请参照图4及图6，本实施例中在卡合件4上还设有第三导向件47，第二导向件45抵接于连接板13的背向拉簧2的一侧，沿Y轴方向，第二导向件45位于第一导向件44与第三导向件47之间。连接板13通过与第一导向件44、第二导向件45及第三导向件47的抵接，来限制卡合件4在导向槽133中的形态，避免卡合件4出现翻转，有利于保证卡合件4的状态稳定。具体地，活塞杆31铰接于卡合件4的第三导向件47处。
可选择地，卡合件4与活塞杆31可以通过球铰进行铰接，当然卡合件4与活塞杆31也可以通过平面铰进行铰接，平面铰的铰轴方向沿X轴方向，卡合件4与活塞杆31优选采用平面铰进行铰接，这样更有利于卡合件4稳定、规律的运动。
请参照图3及图4，为了更好的说明本实施例双向阻尼器200及淋浴门组件的工作过程，本实施例设Y轴正向端的卡合件4为第一卡合件4a，Y轴负向端的卡合件4为第二卡合件4b，Y轴正向端的限位件为第一限位件，Y轴负向端的限位件为第二限位件，Y轴正向端的延伸段132为第一延伸段132a，Y轴负向端的延伸段132 为第二延伸段132b，Y轴正向端的导向槽133为第一导向槽133a，Y轴负向端的导向槽133为第二导向槽133b；Y轴正向端的活塞杆31为第一活塞杆31a，Y轴负向端的活塞杆31为第二活塞杆31b。
假设初始状态下活动门板100处于开门状态，第二限位件位于第二卡合件4b的卡口中，第二卡合件4b处于主体段的第二导向槽133b中，第一限位件与第一卡合件4a处于分离状态，第一卡合件4a位于第一延伸段132a处，第一卡合件4a的第一导向件44抵接至第一延伸段132a上，第一卡合件4a的第一卡齿41下沉于安装架1的上腔18中。
在初始状态下关门时第一卡合件4a及第一活塞杆31a工作过程为：用户手动将活动门板100沿Y轴正向移动，第一卡合件4a跟随活动门板100一起沿Y轴正向移动，直至第一卡合件4a运动至第一限位件，由于第一卡合件4a的第一卡齿41沉于上腔18中，因此第一卡合件4a的第一卡齿41能顺利从第一限位件的下方经过，第一限位件与第一卡合件4a的第二卡齿42接触，第一卡合件4a的第二卡齿42在第一限位件的阻挡下不能沿Y轴正向继续运动，活动门板100继续沿Y轴正向运动；随着活动门板100的继续运动，第一卡合件4a相对活动门板100沿第一导向槽133a滑动，第一活塞杆31a向阻尼缸3的缸腔中回缩，阻尼缸3开始对活动门板100的关门动作产生阻尼，活动门板100在阻尼缸3的阻碍下完成关门运动，并且在第一卡合件4a相对安装架1完全滑至主体段131后，第一卡合件4a的第一卡齿41在第一导向槽133a的引导下露出至上腔18之外，第一限位件被限制在第一卡合件4a的卡口46中。
在初始状态下关门时第二卡合件4b及第二活塞杆31b工作过程为：用户手动将活动门板100沿Y轴正向移动，第二卡合件4b在第二限位件的限制下不能跟随活动门板100一起沿Y轴正向移动，第二卡合件4b相对安装架1沿第二导向槽133b向第二延伸段132b回位，直至第二卡合件4b移动至第二延伸段132b时，第二卡合件4b的第一卡齿41向下沉入上腔18中，第二卡合件4b的第一卡齿41与第二限位件脱离。
开门过程与关门过程中双向阻尼器200的工作过程类似，这里不再赘述。
可选择地，拉簧2可以为两根，两根拉簧与两个卡合件4一一对应，拉簧的一端 与安装架1连接，拉簧的另一端与与对应的卡合件4连接；当然，请参照图4，拉簧2也可以为一根，拉簧2的两端分别与两个卡合件4连接。优选拉簧2为一根，这样有利于减少双向阻尼器200的零件数量，降低双向阻尼器200的生产难度，有利于双向阻尼器200的结构简洁，有利于提升经济性。
可选择地，阻尼缸3还可以设为一个，并且该阻尼缸为双腔缸，两个缸腔分别对应一根活塞杆31。
优选地，请参照图6，第一卡齿41为弯折结构，第一卡齿41包括第一弯折段411、第二弯折段412和第三弯折段413，沿Y轴方向，第一弯折段411的远离第二卡齿42的一端与卡合件4的主体部分连接，第一弯折段411的靠近第二卡齿42的一端与第二弯折段412连接；第二弯折部从第一弯折部上向Z轴负向弯曲，第二弯折段412的Z轴负向一端与第三弯折段413连接；第三弯折段413从第二弯折段412向Y轴方向(Y轴正向或Y轴负向均可)弯曲，第二弯折段412上设有倾斜引导面4111，倾斜引导面4111位于第二弯折段412的朝向Z轴正向的一侧，沿Y轴方向，倾斜引导面4111位于第二弯折段412的背离第二卡齿42的一侧。
由于倾斜引导面4111的设置，使得在活动门板100开关门过程中卡合件4到达限位件时，即使第一卡齿41露出了上腔18之外并与限位件产生了干涉，限位件也能在倾斜引导面4111的引导下迫使第一卡齿41下沉回上腔18中，继而使第一卡齿41顺利从限位件下方通过，有利于双向阻尼器200持续保持正常运行。
卡合件4在随活动门板100运动到达限位件时，之所以需要第一卡齿41通过限位件，是因为在活动门板100反向运动时，能够通过第一卡齿41与限位件的配合，带动卡合件4顺利回到延伸段132的导向槽133中，这样双向阻尼器200才能重复发挥产生阻尼的功能。然而，即使这样仍然可能出现卡合件4在与限位件脱离后未回到延伸段132的情况，例如卡合件4在与限位件脱离后又回到了主体段131，这时主体段131会限制第一卡齿41下沉，即使有倾斜引导面4111的引导，第一卡齿41也不能下沉至上腔18中，导致第一卡齿41不能顺利从限位件下方通过，导致限位件不能顺利到达卡合件4的卡口46中，进而导致在活动门板100反向运动时不能通过限位件与第一卡齿41的配合来带动卡合件4回位至延伸段132，导致活塞杆31始终处于缩回阻尼缸3中的状态，导致阻尼缸3不能继续对活动门板100 的运动产生阻尼，导致双向阻尼器200失效；因此本实施例中将第一卡齿41设为弯折结构，这样即使卡合件4在到达限位件时位于主体段131，限位件也能通过将第一卡齿41挤压变形迫使第一弯折段411向下弯曲，继而使第一卡齿41通过限位件，保证限位件能够顺利到达卡合件4的卡口46中，保证卡合件4在与限位件脱离时已经顺利回位至延伸段132，有利于双向阻尼器200长期保持正常运行。
更优选地，卡合件4上设有限位结构，限位结构具有开口朝第二卡齿42的限位腔43，第二弯折段412穿设于限位腔43的开口中，第三弯折段413位于限位腔43中，限位结构限制第三弯折段413脱离限位腔43，第三弯折段413与限位腔43的底壁之间具有间距。这样，在卡合件4回位的过程中，限位件与第二弯折段412抵接，避免限位件卡至第一弯折段411下方，保证限位件与卡合件4能够在卡合件4回位至延伸段132后顺利脱离；并且，在限位结构的限制下，除了第一弯折段411能进行有限的下沉变形以及恢复形变之外，限位结构限制第二弯折段412沿Y轴方向变形，并通过限制第三弯折段413脱离限位腔43来限制第一弯折段411的变形范围，保证第一卡齿41的形态稳定，保证第一卡齿41的变形可控。
最后需要强调的是，以上所述仅为本发明的优选实施例，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种变化和更改，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业应用性
本发明的双向阻尼器安装在淋浴门组件中，本发明提供的淋浴门组件安装在卫生间内，并且作为淋浴房的重要构成部分，淋浴房可以是带有底盘的整体式淋浴房，也可以是将淋浴门组件安装在两面相邻并且形成夹角的墙壁之间，由活动门板、固定门板以及墙壁围成淋浴房。双向阻尼器固定在活动门板的顶部或底部，通过双向阻尼器与门框上的限位件配合，来对活动门板的开关门运动提供缓冲，避免活动门板与门框高速碰撞，降低淋浴门组件的使用噪声。
